Investigating the Effect of Surface Area on the Rate of Reaction

The video tutorial explores how surface area affects the rate of chemical reactions, focusing on marble chips reacting with hydrochloric acid. It introduces collision theory and presents two experimental methods: measuring the time for marble chips to disappear and collecting carbon dioxide gas. The tutorial emphasizes that increasing surface area increases reaction rates and provides equations to calculate these rates.

What is the expected outcome when using finer marble chips in the reaction with hydrochloric acid?

Explain how the volume of gas collected can be used to calculate the rate of reaction.
